近年来,重磁反演方法有了很大进展,规格化全梯度方法便是其中的一种所谓“非线性变换”方法。这种方法由于利用了规格化全梯度函数,所以在向下半空间延拓过程中能稳定地求出奇点的位置。本文通过理论模型的试算和矿区实际验证表明,该方法不仅可以确定场源的深度,而且对磁性体的倾向也可作出判断。因为所获得的结果是以规格化全梯度场的闭 In recent years, great progress has been made in the method of gravity and magnetic inversion, and the normalized gradient method is one of the so-called “nonlinear transformation” methods. Since this method uses the normalized gradient function, the position of the singular point can be stably obtained during the continuation of the lower half space. In this paper, the trial calculation of the theoretical model and the actual verification of the mining area show that this method can not only determine the depth of the field source, but also judge the tendency of the magnetic body. Because the results obtained are normalized gradient field closed
